Application iiled December 2, 1890. Serial No. 373,321. (No model.)

To all whom it may concern:

Be it known that I, MATHIAS J. IIINDEN, a citizen ofthe United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Steam-Engines, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to certain new and useful improvements insteam-engines.

The invention has for its object the con` struction ot` asteam-generator especially designed for use in producing and supplyingsteam to an engine only in such'quantity as is required for immediateuse in driving` an engine-or, in other words, that will generate steamonly as water is fed to the generator and as the same is required by theengineand wherein the employment of a so-called steam-boiler7 isobviated.

The invention has still a further object in the providing of means forconverting the exhaust-steam into hydrogen gas, which latter iscommingled with the products of combustion and burns with the primarylire employed for heating the generator. In a broad sense the inventionmay properly be classed asa hash-engine.

The invention consists in the peculiar construction, arrangement, andvarious combinations of the parts, all as more fully hereinafterdescribed, and pointed outin the claim.

Figure I is a top plan ot my improved engine. Fig. 2 is a sideelevaiion. Fig. 3 is an elevation at right angles to Fig. 2. Fig. 4 is avertical section on the line c of Fig. 1 with the engine removed. Fig. 5is a sectional elevation of" the gas-generator detached.

In the accompanying drawings, which form a part of this specification, Arepresents a steam-generator, which consists of an iron ring a, to whichare bolted or otherwise secured with, steam-tight joints the lower plateb and the upper plate c, which may be of any suitable metal, though Iprefer steel.

For the purpose of compactness I show an `an engine B as mounted uponthe top of the generator A. A steam-pipe C conveys steam from thegenerator to the valve-chest of the engine.

Eis apump, which in large engines should be arranged to be automaticallyoperated by the engine; but in the drawings it is shown as separatedtherefrom and is designed to be operated by hand. The suction-pipe ofthis pump communicates with a suitable waterreservoir F, while the feedor discharge pipe F of the pump passes to the interior' ofthe generatorA beneath the upper plate thereof, its inner end being turned down at orabout the axial center of the lower plate of the generator, as shown.

G is the exhaust-pipe from the engine. The outer end of thisexhaust-pipe is connected to one end of a gas-gen erating cylinder II,which latter is filled or partially filled with tacks, nails, orparticles of iron. The opposite end of the cylinder H is provided with apipe I, which latter is bent so as to bring its free end below thecylinder H and at or about its lougitudinal center.

In the drawings I represent the steam-generator as mounted upon legs J,and in small engines where gas can be employed as the -below the centerof the generator, and after it has been heated I force Water from thepump into the feed-pipeF, the free end of which is provided with asm'all hole or opening, through which the Water escapes ldrop by drop orin a very small spray and falls upon the heated lower plate ot thesteam-generator y and which immediately converts the water into steam.From the generator the steam passes to the engine through the steam-pipeC. The exhaust-steam from the engine passes to the enlarged cylinder H,where it is impeded by the heated particles of iron within suchcylinder, generating a hydrogen gas,

which escapes through the pipe I and com- IOO *i November, 1890.

cylinder being filled or partially filled with particles of iron, and asteam-exhaust pipe communicating with both ends of said cylinder as ameans for converting the exhauststeam into hydrogen gas, substantiallyas and for the purposes described. Y
